Federated Identity Propagation

This feature thread tracks the evolution of propagating user identity across federated Kubernetes and AI platforms. Initial efforts focused on the challenges of maintaining a unified user experience and security posture across distributed environments. The central identity gateway pattern has emerged as a key solution, enabling a single sign-on experience and consistent identity context for users interacting with multiple clusters and AI services.

The architecture uses standard OpenID Connect, a minimal /gateway/userinfo validation endpoint, stateless regional gateways, and a shared Redis-backed session store with explicit TTLs. Centralized session ownership coordinates token refresh and logout platform-wide, reduces upstream identity-provider load to scale with active users rather than user-tool combinations, and standardizes identity headers for downstream services. Security guardrails include mutual TLS or workload identity between gateways, stripping inbound identity headers before injecting trusted ones, and defining explicit failure behavior for session-store unavailability.
